Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of test — Part 11: Determination of crystallizing point (Excluding cresylic acid and xylenols)

The test may be carried out on products as received or on a dried sample. The method specified in ISO 2208 shall be applied for drying. The principle of the method consists in cooling the liquid or liquefied test portion and observation of the temperature during crystallization under defined conditions. A simplified crystallization point apparatus is given in the figure. It takes into account the properties of these products.
